Helix Anchor, 10.261 lb

A helix anchor (helical anchor or screw anchor) is a deep foundation system used in overhead transmission and distribution line construction to provide high-capacity tensile and lateral resistance in varied soil conditions. It consists of a central steel shaft with one or more helical bearing plates welded along its length. The anchor is mechanically rotated into the ground, transferring structural loads from guy wires and pole structures into competent soil strata through end-bearing and friction.

In power line applications, helix anchors are primarily deployed for guyed poles, dead-end structures, angle towers, and temporary line supports. Their predictable load capacity, minimal site disturbance, and rapid installation make them suitable for both greenfield transmission projects and grid reinforcement works.

Key Features

• High Tensile Capacity: Designed to resist uplift and lateral loads generated by conductor tension and wind loading.
• Helical Bearing Plates: Engineered plate geometry ensures efficient load transfer to stable soil layers.
• Hot-Dip Galvanized Steel: Corrosion-resistant coating for long-term durability in aggressive soil environments.
• Torque-Correlated Capacity: Installation torque provides real-time verification of holding capacity.
• Minimal Excavation: Installed without large-scale digging, reducing environmental impact and restoration costs.
• Adaptable Shaft Configurations: Round or square shafts available to suit specific soil profiles and structural loads.
• Rapid Installation: Mechanized installation reduces labor requirements and project timelines.
• Removable and Reusable Options: Suitable for temporary structures and staged grid expansion projects.
